Some of the following instructions must be executed with root privileges.

Installing fetapd

  1. Clone this repository (together with pylinphone as sub-module)

    cd /opt
    git clone https://git.blinkenbunt.org/LUG-Saar/fetapi.git
    git submodule update
  2. Configure and enable fetapd as systemd service

    ln -sr fetapd.service /etc/systemd/system/
    systemctl daemon-reload
    systemctl enable fetapd

Installing linphone-cli on Raspbian

  1. Install debootstrap

    apt install debootstrap
  2. Create a Debian/sid chroot environment

    cd /var/tmp
    mkdir debian-sid
    debootstrap --arch=armel --foreign --variant=minbase sid ./debian-sid http://ftp.de.debian.org/debian
    chroot debian-sid/ /debootstrap/debootstrap --second-stage

    Note: Without --variant=minbase, sound won't work for some strange, unknown reason.

  3. Install linphone-cli inside the chroot environment

    chroot debian-sid/ apt -y install linphone-cli
  4. Create user inside the chroot environment

    chroot /var/tmp/debian-sid adduser --disabled-password pi
  5. Bind-mount /dev to make ALSA accessible within the chroot

    cat <<EOF >>/etc/fstab
    /dev /var/tmp/debian-sid/dev none bind 0 0
    mount -a
  6. Copy Linphone configuration file

    cp linphone.conf /var/tmp/debian-sid/home/pi/
  7. Configure and enable linphone-daemon as systemd service

    ln -sr linphone-daemon.service /etc/systemd/system
    systemctl daemon-reload
    systemctl enable linphone-daemon

Configuring fetapd


Identifying soundcard

# chroot /var/tmp/debian-sid /usr/bin/linphonec
linphonec> soundcard list
0: ALSA: default
1: ALSA: bcm2835 Headphones
2: ALSA: C-Media USB Headphone Set

Starting fetapd

systemctl start fetapd

(or simply reboot your FeTAp)
